HEADLIGHT.

Specification of Letters Patent.

Application filed May 15, 1314. Serial No. 838,779.

To all/whom it may concern:

Be it known that I, ADAM FREDRIOK KUsH, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Headlights, of which thefollowing is a specification.

This invention relates to lamps, and more particularly to lamps commonlyknown as headlights for use on motor vehicles. I

It is'well known that the headlights now in use are very offensive topedestrians on the city streets, due to the intense brilliancy of thesame, and in some cases there have been city ordinances passedprohibiting a lamp of undue brilliancy being used in the city limits. Ithas, therefore, been necessary in many cases to use dimmers or modifiersfor the headlight of motor vehicles, or to provide a separate set oflamps for city service and extinguish the large lamps.

This, of course, entails a larger expense on the owner of the vehicle,and necessitates the, use of a complicated device for dimming theheadlight.

The object of my invention is to overcome the aforesaid objections, andto provide a headlight in which the brilliancy of the same may bequickly and effectively reduced or increased without the use ofcomplicated shutter operating mechanisms.

- Another object of my invention is to provide a headlight whichcontains more than one lamp, thereby providing a means to increase ordecrease the brilliancy of the light.

A still further object is to provide a headlight of the class describedwhich will provide, in the present instance, various degrees ofbrilliancy without the usual use of I complicated mechanisms forshutting off the construction, combination and arrangement light.

Other objects and advantages of my in- 'vention .will appear as a morethorough understanding of the same is attained.

The invention resides preferably in the of parts as shown in thedrawing'and described in the specification and claims.

In the accompanying drawing, Figure 1 is a longitudinal sectional viewof a headlight of the class described embodying the preferredform of myinvention. Fig. 2 is a front elevation of the same. Fig. 3 is atransverse sectional view on the line 33 of Fig. 1..

. and in spaced relation thereto.

Referring more particularly to the drawmg, the numeral 1 indicates alight containing chamber or casing substantially frusto-conical inshape, and provided with the transparent face 2 secured in position onthe open end of the said casing 1 by means of the annular ring 3. Therearwall -of the aforesaid casing 1 is substantially concavo-convex asshown at 4, and a source of light, in the present instance an electricincandescent lamp 5, is supported therein. The electric light 5, asshown in the drawing, is supplied from a source of current by means ofthe wires 6.

Supported within and in spaced relation to the aforesaid lightcontaining chamber 1 Patented ly 27,1915.

is a supplementary light containing cham- Supporting means 8 areprovided extending inwardly from the aforesaid casing 1 V and secured inthe supplemental casing 7, so as to support the same within the casing 1have shown the said supporting means of a rigid character, it will beunderstood that the same may be adjustable so as to support the interiorchamber 7 at any position or adjust the same in central position to thecasing 1. t

I provide within the interior chamber 7 a lamp 9 shown in" the drawingto be an incandescent electric lamp. In order to supply electric currentto the said lamp 9, or if the same were a gas lamp, in order to supplygas to the same, I provide a conduit 10 formed in the rear Wall withinthe said IVhileI casing 7, said conduit 10 being in commuincandescenttype, wires 14 are provided for supplying electric current to the same.The wires 6 and the wires 14 are independently controlled by switches onthe dashboard of the vehicle, the 1 said switches not being shown as itis not thought they are necessary in the present instance.

In use when it is wished to obtain a dim light the lamp 5 is lighted andthe radiance emanating-from the said lamp 5 willpass out inltheform ofan annular ring of light. said ring of light being formed by virtue ofthechamber'j' being in spaced relation to the chamber 1 andthe'periphery15 of the said chamber 7 together with the inner periphery 15' of theouter'chamber 1 will provide. an. annular space. 16 between the .saidinner and'ou'ter chambers,aand thus provide the aforesaid rlngof light.To ob- It will be seen from the aforesaid descrip thin that I haveprovided a headlight, which is both cheap to manufacture and simple inconstruction, and while I have shown aspecific arrangement of parts andconstruction, it will be readily lmderstood by those skilled in the artthat certain minor changes in the details, such as the substitution of agas for an electric lamp may be made, without departing from the spiritand scope of the invention.

What I claim and wish to secure by Letters Patent is 1. A device asspecified, including a plurality of concentrically arranged casings,

each of which is provided with an independent light source, all of saidlight sources being capable of use independently or collectively to varythe intensity of the light, substantially as described.

A device as specified, including a plu-,

rality of permanently arranged nested casings and a lighting elementassociated with each of said casings, capable of lighting,"

3. A device as specified, including a plurality of permanently spacedapart nested casings, light sources associated with each casing andcapable of independent or collective control relative to each other, substantially as described.

4. A device as specified, including a plurality of concentrically nestedcasings, each of said casings being in spaced relation to each other,light sources associated with each of said casings, said light sourcesbeing independently or collectively controllable, and adapted to projectlight between the said concentric casings, substantially as described.

5. A device as specified, including a plurality of nested casings, meansfor supporting the aforesaid casingsin permanent spaced relation, and alight source provided .in each of said casings, capable of lightingcollectively or independently,- substantially as described. I I a 6. Adevice as specified, including a plurality of spaced apart nestedcasings, a lamp associated with each, bracket elements for supportingthe casings in spaced relation, and certain of said supportingelementscom prising means for supplying an illuminating agent to each of saidlight sources.

7. A device as specified, including a plu-' rality of spaced apartnested casings, light sources associated with each of said casings andadapted for collective or independent illumination, the inner surface ofsaid casings provided with reflector means, and the portion adjacent thelight source being substantially concavo-convex in contour, whereby toform areflector for said light source.

8. A device as specified, including a plurality of concentrically nestedcasings, said casings being substantially frusto -conical in contour, alight source in each capable of independent or; collective lighting,said casings being substantially similar in configuration.

9. A device as specified, including a plurality of spaced apart nestedconcentric casings, and" a light source in each arranged substantiallyin alinement with the longi-- tudinal axis of the concentric casings andcapable, of independent or collective use.

In testimony whereof I aflix my signature in presence of two witnesses.
